The attached project demonstrates how to utilize RasterImage.GetPixelColor() along with a basic Nearest Neighbor Search implementation to find the nearest pixel of a given color to the cursor.

Right click on any pixel to select a color. Then, double click anywhere on the image to snap the cursor to the nearest pixel of the selected color.

NOTE: The search algorithm is greedy. It will snap to the first-found nearest neighbor of the selected color, even if equidistant neighbors of the selected color exist.
